Production of curie quantities of high purity I-123 with 15 MeV protons

Reaction cross section / Excitation function / nat Te target / Radioisotopes of iodineSummary. The excitation functions of proton induced nuclear reactions on nat Te were measured using the stackedfoil technique up to 14.5 MeV. Samples of thin uniform layers of nat Te on Ti-backing were prepared by electrodeposition. Nuclear reaction cross sections for the formation of 120g,121,123,124,125,126,128,130(m+g) I were determined and their theoretical thick target yields were calculated. The obtained data were compared with the previously published experimental results and the values obtained theoretically using the ALICE-IPPE computer code.

“…The latter three radionuclides are produced using cyclotrons and highly enriched isotopes as target materials. The cross section data have been well documented, especially for protons on Te isotopes [3][4][5][6][7][8][9]. Data on proton induced reactions on nat Te have also been measured [4,[10][11][12][13][14][15][16][17][18][19].…”

nat Te / Proton induced reactions / Radioisotopes 123,124,126,130 I / Excitation function / Integral yield Summary. Excitation functions of the reactions nat Te( p, xn) 123,124,126,130 I were measured from their respective thresholds up to 17 MeV. The conventional stacked-foil technique was used where the samples for irradiation were prepared by a sedimentation process. The measured excitation functions were compared with both the data available in the literature and the results of theoretical calculations using the codes TALYS-1.2 and ALICE-IPPE. The present experimental data show good agreement with TALYS-1.2 calculations but some deviations from ALICE-IPPE results. From the experimental data the integral yields of the investigated radionuclides were calculated as a function of the proton energy. The most dominating product is 130 I.

“…A summary of the direct methods of production [73][74][75][76][77][78][79][80][81][82][83][84] is given in Table 6. These consist of a-and 3 Heparticle induced nuclear reactions on antimony, as well as proton and deuteron induced reactions on isotopically enriched tellurium targets.…”

Production of Some Medically Important Short-Lived Neutron-Deficient Radioisotopes of Halogens

1983

Halogens are particularly useful for designing structural analogues of biomolecules which find application in functional imaging using PECT (e.g. with 1 'F, "Br) or SPECT (with 1 "I). This paper reviews some of the recent information published on the production of 1 · F, 3 4m Cl, " Br, 7 5 Br, 12 3 1 and 2 " At. The nuclear reactions studied, the optimum energy ranges suggested, the thick target yields obtained (or expected) and the radionuclide impurities found in each process are briefly summarized. A short outline of the state of the art of targetry for the production of each radioisotope is given. The radiochemical separation methods are discussed. Wherever possible a critical comparison of the various production routes is given.
